<span>Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.</span>
I think the answer would be c
The purpose<span> of a </span>salt bridge<span> is not to move electrons from the electrolyte, rather it's to maintain charge balance because the electrons are moving from one-half </span>cell<span> to the other. The electrons flow from the anode to the cathode.</span>
I think it's b the answer
